Blocking outgoing traffic doesn't work

Hello,

i was testing something it is really strange. I use glasswire, it may be the culprit perhaps?

I blocked all outgoing traffic in firewall, by selecting block for outcoming in correct network profile i use (i checked again). But i have disable all outgoing core networking rules, all apps. Yet i was still able to connect just with DHCP, DNS and remote port 80,443 to internet in browser i didn't allow in firewall outgoing, or i was able to log in and connect on discord. While I disabled firewall in glasswire and rules were deleted from windows firewall, since it does use windows firewall - it doesn't have third party firewall. I know it is instantenous, but i restared pc yet and still i could connect to internet in programs i didn't allow specifically, while all outbound connections were blocked. IT even said so in monitoring. That is odd! EDIT: Apps were also not allowed in app section of firewall!

I am not sure why you need to block all outbound traffic as that is a bit extreme and difficult to manage plus it won't stop a lot of malware as they will simply use common ports and protocols such as 443 that you will likely have allowed.

I can not speak to Glasswire, but in Windows firewall there are different profiles and it may be the case of the wrong profile selected, an app or process re-enabling/adding a nessecary exception or simply another rule with too broad an allow scope.
